The invention discloses a geomagnetic vehicle detector data conversion method and device, and the method comprises the steps: obtaining vehicle data collected by a space imaging device, determining the position relation between a vehicle and a simulated geomagnetic detection region according to the vehicle data, and determining whether the geomagnetic detection region is occupied or not according to the position relation. Generating a detection state, if the current detection state is different from the previously recorded state, indicating that a new vehicle entering or leaving event occurs in the geomagnetic detection area, determining whether a vehicle enters or leaves at present according to the recorded state, if the detection state is occupied, indicating that a vehicle enters, and if the detection state is not occupied, indicating that a vehicle does not enter; therefore, simulation of the working process of the geomagnetic vehicle detector is realized.
本发明公开了一种地磁车辆检测器数据转换方法及装置,该发明通过获取空间成像设备采集得到的车辆数据,根据该车辆数据确定车辆与模拟的地磁检测区域之间的位置关系,从而依据位置关系确定地磁检测区域是否被占用,生成检测状态,若当前的检测状态与之前记录的状态不同,说明地磁检测区域新发生了车辆进入或离开事件,则根据记录状态确定是当前是存在车辆进入还是离开,若检测状态为被占用,则说明有车辆进入,若检测状态为未占用,则说明有车辆离开,实现了地磁车辆检测器工作过程的模拟。
